CONSTRUCTION OF HYDRANTS FOR FILTRATION.

Specification of Letters Patent No, 25,805, dated October 18, 1859.

To all whom it may concern:

Be it known that I, JOHN H. CARTER, of Cincinnati, in the county ofHamilton and State of Ohio, have invented a new and useful Improvementin Filtering-Hydrants; and I do hereby declare that the following is afull and clear description thereof, reference being had to theaccompanying drawings and to the letters of reference marked thereon andmade to form a part of this specification.

My invention is an improvement in hydrants by means of which I amenabled to filter the water, as it is received from the pipes, and,discharge it, as required for use, properly filtered and freed fromsediment, as hereinafter set forth and represented.

In reference to the accompanying drawings, Figure l, is a perspectiveview of the ltering hydrant, showing the same as being arranged for use.Fig. 2, is a vertical sectional view of the same. Fig. 3, is aperspective View of the filter and receiver.

(A) represents the shell of the upper portion of the hydrant, the lowerportion of which is formed with an annular projecting flange (B) is theshell of the lower portion or receiver of the hydrant, its upper endbeing provided or formed with a flange (o), and its lower end with aflange (c) which affords facilities for securing the base of thehydrant. Secured to the base of the receiver, is a conical elevation(CZ) having in its center, a tube (e) through which water may beadmitted to the receiver Upon the top of said tube (c) is a cap (e) bymeans of which water is prevented from being forced directly against thefilter; the pipe or tube (c) being open upon either side below the cap(c) so as to allow the water to escape into the receiver (B) as shownclearly in Fig. 3. By means of this arrangement, a large portion of theimpurities contained in the water will be precipitated to the bottom ofsaid receiver, before the water comes in contact with the filter, and bymeans of the cock the sediment, and impurities contained in the water,and which may be deposited at the bottom of the receiver, may bedischarged, whenever it may be desired to cleanse the said receiver.

(g) is a cylinder formed open at the top and bottom, and having a flange(g) which is adapted to fit between the flanges (o) and (o) by means ofwhich said cylinder may be secured in its proper place for use andremovable; in such manner that there shall be a space around and betweenit and the shell (A) within which it is arranged.

(L) is a perforated disk made to fit closely within the cylinder (g) andmay be secured therein by means of the ring and rods (2) which aresecured to said cylinder, directly under said disk (it) and drawntightly across it, is a piece of woolen cloth (Z). The said cylinder (g)will then be filled with fine granulated charcoal, between the disk (7L)and the strainer which is of woolen cloth, and secured by means of thering (7c) 1s a perforated cap, lined and covered with cotton fiannel, orother suitable material as clearly shown in Fig. 3.

(m) is a waste water pipe, communicating with the upper portion (A) orreservoir of the hydrant.

(a) is a cock by means of which the filtered water may be withdrawn fromthe hydrant.

The filter being properly prepared as before described, it will beinserted within the shell or reservoir (A) as shown in Fig. 3, havingsuitable packing between its flange (g) and the ange (a) of saidreservoir, and also between its said flange (g) and the flange of thereceiver (B), the whole will then be secured firmly together, by meansof bolts (p).

The hydrant being properly arranged for use the water will pass upthrough the pipe (e) strike against the cap (c) and be thereby deflecteddownward as before described. As the receiver (B) becomes filled, thewater will be forced up, first through the strainer (l) then through thegranulated charcoal, then through the second strainer then through thespace (s) which will be filled with fine, washed sand, and then throughthe perforated cap and its cotton flannel. The cotton flannel, beingvery close and firmly woven, serves to retain any impurities in thewater, or, any particles of coal that may be forced up through the sand.

the cap, e', for favoring the direction of the l sediment downward inthe manner and for 10 the purpose set forth.

In testimony of Which invention I have hereunto set my hand.

JOHN H. CARTER.
